“Guiding Light” and Marvel Comics have teamed up for an episode of this long-running series, to be shown at 10 a.m. tomorrow on CBS. In the episode, “She’s a Marvel,” Beth Ehlers, as Harley Davidson Cooper, one of the show’s main characters, has an accident that gives her superpowers. To commemorate the occasion, Marvel has produced an eight-page comic.

The episode is a mix of slapstick (a thief is shocked by the heroine, and his hair stands on end) and drama (are the powers worth possibly losing her husband?). Transitions between scenes feature comic book panels by Alex Chung.

Mr. Chung is also the artist of “A New Light,” the eight-page story from Marvel that is commemorating the collaboration. The story will be included in several Marvel titles, arriving last week, today and on Nov. 8.

The script for “A New Light” was a balancing act, said Jim McCann, the writer of the comic. He said he had to give readers enough information about “Guiding Light” characters and also fill them in on Marvel superheroes and villains.

“I tried to make it as universal and as accessible as possible for both sides,” Mr. McCann said. “I threw in a couple of little things for ‘Guiding Light’ fans, so they would know I really did my homework on their show.”
